After reading all the wire topics, wiki and reply's. I also want to build a LME49600 headphone amp. But the smd parts are to small for me to handle. The LME49600 is just the limit. So i made a PCB with power supply with normal through hole parts.

The pcb design is just one layer so it is easy to make yourself. Size 100x100mm or 100x160mm.

After building i compaired it, to my 300b tube headphone amp, Lehmann Linear headphone amp and a view other DiY headphone amps with my AKG 701 and i like this one the best. It has the wide soundstage of a tube amp but with better bass controll. No noise, no humm, no distorsion.
